Emulator fe config path hardcoded and no safeguard
If the scanConsole is executed from a folder different from the src folder, the emulator fe config can not be found.
-> Opening controller config: ../configs/emuCfg.json -> Found Emulator config -> Starting Emulator configs/emu_fe0.json terminate called after throwing an instance of 'std::invalid_argument' what(): parse error - unexpected end of input Aborted (core dumped)
Add safeguard with proper error message that file could not be found.
